Specification of Letters Patent.

Patented April 7, 1908.

Applicationfiled March 12, 1907. Serial No. 362,001.

To all whom it may concern:

Be it known that 1, JAMES EDWARD PUR- SER, a subject of the King of Great Britain, residing at Windsor, in the county of Essex and Province of Ontario, Canada, have invented certain new and useful Improvements in a Se arator for Separating CondensationWater om Steam, of which the following is a specification.

My present invention is designed to provide certain new and useful improvements in a separator for separating condensation water from steam in a steam system, and to provide means also for returning the water to the boiler.

My present invention is designed more particularly as an improvement upon a compound separator for this purpose embodied 1n an application for United States Letters Patent filed by James Edward Purser, March 8, 1906, Serial No. 304,981, my aim being to accomplish the results desired in a more simple, economical and superior manner.

Accordingly my invention consists of the construction, combination and arrangement of devices hereinafter described and claimed and illustrated in the accompanying drawings, in which,

Figure 1 is a view in perspective illustrating my invention. Fig. 2 1s a view in side elevation showing features of the invention. Fig. 3 is a view in vertical section. Fig. 4 is a vertical cross section of certain features of the mechanism. Fig. 5 is a view in vertical longitudinal section, illustrating features of the invention.

A special purpose of the present invention, as in that embodied in the application above referred to, is to provide a separator of this nature which will take care of any required amount of condensation water in steam systems in a simple and eflicient manner, or water led thereto in any manner.

I employ two tanks or chambers, the one a stationary tank and the other a tilting chamber, my invention providing means whereby the water may be received into and discharged from both of said tanks or chambers, and also whereby the water may be discharged from the stationary tank more rapidly or in larger volume, if desired, than from the tilting tank, provision being made also whereby steam may be led into both the tanks, the entrance of steam into the two chambers being controlled preferably by a single valve.

My present invention more especially contemplates a different arrangement of the weighted lever for maintaining the normal center of gravity for the tilting tank. Also the method of mounting the trunnions upon the base.

I carry out my invention as follows:

It will be noted that various features are practically the same as those embodied in said application. Accordingly in the drawings a represents any suitable base, upon which are engaged horizontal hollow trunnions b, c, the same being shown separated by a diaphra m d. The base is channeled or chambered as indicated at e and f to communicate through the corresponding trunnions. Supported upon said trunnions is a steam pipe communicating with the trunnion c, said pipe leading into a tilting receiving tank k supported upon said steam pipe at one side the center of gravity of said tank. The steam pipe j communicates into said tank, as by means of an interior pipe 9 leading into one end of the tank above the normal water level in said tank. A water pipe h communicates with the water channel or chamber 6 of the base to lead water therethrough into the hollow trunnion b, said trunnion communicating through a pipe i into the tilting tank,

and whereby water is led 'into the tilting tank.

A stationary storage tank or receiving chamber is indicated at l with which the wa ter pipe h communicates, as through a branch pipe m. Connected with the base of the receiving chamber 1 is a discharge pipe n to carry the water from the stationary tank to the boiler. This discharge pipe n may be of any desired size in cross section. A steam pipe 19 leads into a steam chamber q in the ase a, the steam admission chamber 9 communicable with the steam channel f of the base, the communication being controlled by a suitable valve 1' provided with a stem .9 with which is pivotally connected a weighted levert engaged with a yoke it. From the steam channel or chamber f leads a steam pipe 1) to the stationary storage tank Z.

It will be evident that steam entering through the pipe 1) into the channeled base may pass into the steam channel when the valve 1" is open, the steam from t e channel 7 passing through the trunnion c and pipe 9' into the tilting tank and at the same time through the pipe 4) to the stationary tank Z, the steam passing into both of said tanks on top of the water accumulated therein so that steam pressure is exerted on the top of both of said tanks to drive the water out therefrom.

It will be understood that the tilting and stationary tanks are designed to be set a suitable distance above the water line of the boiler into which the condensation water is to be fed. The receiving tank 7c being supported at one side of the center of gravity by the pipe j upon said trunnions, will obviously tilt when the water has accumulated therewithin sufliciently to overcome the normal center of gravity maintained by means of a weighted lever which is indicated at w. In the present case said lever is supported above the tilting tank upon a yoke which may consist of uprights :0, it upon opposite sides of the tilting tank, the lower extremities of the uprights ac, a: being engaged in any suitable manner with the base a. The uprights are provided with a cross arm y supporting a bearing 2 in which arms or pins, indicated by the numeral 6, with which the lever to is provided, are journaled. The u rights 1r may simply consist of pipes screwec into the base. The rear end of the lever w is engaged with a rocking yoke 7 carried by a bearing 8 engaged upon the pipe 1', or in other words with a pipe fitting 9 interposed in said pipe "11. The steam channel f communicates with asteam channel 10 in the base to provide for the escape of air from the tanks as water accumulates therein, the air passing through the pipes g, j, and r and through the trunnion c.

To govern the discharge of air through the channel 10 I provide an additional valve mechanism indicated at 11, the same being actuated by a weighted lever 12 connected with the valve stem 13 and being supported upon a yoke 14. At the rear end of the tiltmg tank is an upright rocking arm 1 5, the tank. being provided with a rearwardly extendedarm 16, through which the rocking arm 15 is sleeved. The rocking arm 15 is provided with buffer springs indicated at 17 and 18, the one located above and the other beneath the arm 16. Connected with the arm 16 is an additional pendent arm 20, said pendent arm provided with a stirrup 19 through which the weighted lever 15 projects, and whereby the steam valve mechanism 1 is actuated when the tank 7c tilts. The lower end of the pendent arm 20 is also provided with a stop collar indicated at 21 which actuates the lever 12, the stop collar 21 being adjustable. To receive the trunnions b, c and to form the chambers or channels e, f, the base is constructed with upwardly extended chambered brackets 22 and 23 into which the trunnions communicate, the trunnions rocking in journal plates 24 and 25 provided with inwardly extended arms 26 and 27 respectively, upon .Which are engaged packing nuts indicated at 28 and 29. The employment of these journal plates 24 and 25 forms a very simple and economical manner of mounting the trunnions, said plates being united to the corresponding brackets 22 and 23 by bolts 30 and nuts 31 thereupon.

To prevent back pressure in the discharge of the tanks in the inlet water pipe, the same is provided with check valves 32 and 33 located on opposite sides of the branch pipe m. It is evident that the tilting tank may discharge into the discharge pipe 12 as by means of a pipe 34 leading into the discharge pipe, the pipe 34 being provided with a check valve 35 to close said pipe against back pressure. The pipe a may also be provided with a check valve 36. I do not limit myself, however, to having the discharge from the tilting tank led into the discharge pipe n, as

it might be led to a boiler or otherwise entirely independent of the discharge pipe from the stationary tank.

My present improvement will now be understood and the operation of the same. The tilting tank obviously serves to automatically admit steam upon the water in both tanks to force the water to the boiler. The check valves above described all open to the boiler and are closed by the steam pressure from the boiler. The brackets have bolt holes cored therethrough about the corresponding channels or chambers, the bolts thus being independent of the steam and water passages.

What I claim as my invention is:

1. A separator for a steam system comprising a base constructed with upwardly extended chambered brackets on opposite sides thereof forming on one side a water chamber and on the other side a steam chamber, journal plates formed with outwardly projecting flanges engaged against the inside faces of said chambered brackets and with inwardly projecting tubular arms, hollow trunnions journaled in said tubular arms respectively, packing nuts engaged upon said trunnions and upon the inner extremities of the corresponding tubular arms, a tilting receiving chamber, a steam pipe supporting said receiving chamber communicating with one of said trunnions and with the receiving chamber, a water pipe communicating with the other of said trunnions and with the receiving chamber, said brackets each formed with an opening whereby the corresponding chamber communicates with the corresponding trunnion, and bolts passed through the flanges of the journal plates and through the bolt holes of the corresponding brackets outside the corresponding chambers.

2. A separator for a steam system comprising a support, a tilting receiving chamber, hollow trunnions supporting said chamber upon said base, a water pipe underneath the receiving chamber communicable with said chamber and movable therewith, whereby water is led from one of said trunnions into said chamber, a fixed yoke carried by the support on opposite sides of said chamber and provided With across arm extending over the receiving chamber, a tilting lever fulcrumed upon said cross arm above the receiving chamber, a weight upon the forward end of said lever, and a rocking yoke With which the rear end of the tilting lever is engaged, the lower ends of said rocking-yoke ournaled u on said water pipe and vertically rnovab e therewith.

3. A steam separator for a steam system comprising a support, trunnions mounted upon said support, a tilting receiving chamber mounted upon said trunnions, a water pipe underneath the receiving chamber movable with said chamber and connecting one of said trunnions with said chamber, a fixed yoke carried by the support and extended over said chamber, a lever mounted upon said yoke above the receiving chamber, a Weight upon the forward end of said lever, and a rocking yoke journaled upon said water pipe and movable therewith, with Which the rear end of said lever is engaged, said lever holding the receiving chamber in position to receive water of condensation until the weight of Water in said chamber overcomes the action of the Weighted lever, sub stantially as set forth.

In testimony whereof I afiix my signature in presence of-two Witnesses.

JAMES EDWARD PURSER.
